What is POM-H+PTFE?
POM-H+PTFE is a unique thermoplastic blend that combines the high mechanical strength of Acetal Homopolymer (POM-H) with the exceptional lubricity of Polytetrafluoroethylene (PTFE) fibers. By dispersing PTFE fibers uniformly within the acetal resin, manufacturers create a material that is both “tough” and “slippery.”
At Cylex Plastics, we specialize in providing this high-performance material to meet the rigorous demands of global industrial sectors.
Key Benefits for Mechanical Parts
1. Superior Wear Resistance
Standard plastics often degrade quickly under constant friction. The integrated PTFE fibers in POM-H+PTFE act as a built-in lubricant. As the part moves, a microscopic layer of PTFE is transferred to the mating surface, drastically reducing the wear rate and extending the service life of the component.
2. Low Coefficient of Friction
Because PTFE is one of the most “slippery” substances known to man, this blend offers a much lower coefficient of friction than standard POM-C or POM-H. This results in smoother operation, less heat generation, and reduced energy consumption for driven machinery.
3. Dimensional Stability and Strength
While pure PTFE is soft, the POM-H base provides the structural integrity needed for load-bearing parts. It maintains excellent dimensional stability, meaning parts stay within their tight tolerances even under varying environmental conditions.
4. Elimination of “Stick-Slip”
In many mechanical systems, “stick-slip” (the jerky motion caused by friction) can cause vibration and noise. POM-H+PTFE ensures a consistent, fluid movement, which is critical for precision instruments and high-speed conveyors.
Common Applications
- Bushings and Bearings: Ideal for high-load, high-speed applications where external lubrication is impossible.
- Gears and Cams: Provides quiet operation and long-lasting tooth profiles.
- Thrust Washers: Reduces friction between rotating components.
- Sliding Elements: Used in guides and rails to ensure smooth linear motion.
